Abstract
A screen frame and screen are secured into sealing engagement within a screening machine by a screen frame sealing mechanism and method which allows the user to simultaneously raise an entire side of the screen frame into sealing engagement. Advantageously, the entire screen frame can be raised into sealing engagement to prevent the escape of fine material being screened and avoid metal-to-metal contact during the screening process from a single location.
